Qt GUI for reprounzip

[remram44]

See also #132

This adds a GUI for reprounzip written using PyQt4.

There are two dialogs, one to run an unpack an experiment to a directory, and one to run an unpacked directory. The first can be opened from the second, and double-clicking on an RPZ file would bring you to the first where unpacking would switch to the second.

_First tab, unpacking an .rpz file. To use an existing unpacked directory, switch to second tab_

_Unpacking shows feedback then switches to second tab_

_Directory set automatically when unpacking_

_Running launches the system terminal_

_Removing the experiment shows feedback_ - [X] GUI - Run experiment in native system terminal - [X] OSX (through ugly AppleScript) - [X] Windows (cmd.exe supports this) - [X] Linux (need to try terminals until one works: konsole, gnome-terminal, lxterminal, rxvt, xterm) - [X] Unpack/destroy - [ ] Only show available unpackers - [ ] Input/output file management - [x] Select runs - [ ] Set app to open when double-clicking .rpz file

@VickySteeves says that tabs would be better than windows (and first dialog should be default when opening the app without argument).

I added a built-in "terminal" that shows the output from unpack/destroy commands as they go, however it is kind of weird to have different types of terminals (builtin vs system one used to run)?
